January 18, 2014: January 2014 was one of the driest Januarys on record in recorded history. Even in winter, much of the vegetation in drought-stricken California appeared brown. Roughly two weeks after this photo was taken, the Sierra snowpack was measured on Feb. 1 at 9 percent of average, the lowest ever for that time of year.

March 1, 2017: After a series of storms slam Northern California throughout January and February, the vegetation greens and the snowpack is at 185 percent of normal.

November 2016: The state was at the tail end of a multi-year drought before the rainy season evolved into one of the wettest in history.

February 2017: A series of winter storms pushed reservoirs in the Sacramento Valley to the brim in January and February 2017. As of February 11, 2017, Lake Oroville stood at 151 percent of the historical average. Folsom Lake was at 144 percent, Lake Shasta was at 138 percent, Don Pedro Reservoir was at 141 percent, and Lake McClure was at 182 percent.

Bottom: Due to the recent rain, water levels have increased at Folsom Lake Marina, one of the largest inland marinas in California, located at Browns Ravine Cove on the south shore of Folsom Lake, January 11, 2017.
